The latest robbery happened April 9 at a TD Bank on Main street in Groveland.

The majority of the armed robberies have been at TD Bank branches in Methuen and Lawrence, although the robber is believed to have been involved in a bank robbery in Dracut as well.

"He brandishes a gun, he's pushed people out of the way. Generally in these types of robberies, we see a note. He has no note. He pushes people around and just demands money, so we have to be concerned," said Lawrence Police Chief John Romero.

The robber is described as white, approximately 5 feet 9 inches tall, 180 to 200 pounds, with brown eyes and thin eyebrows.

He wears a white or black mask, a gray hooded sweatshirt, blue zippered jacket or sweatshirt with a white logo, faded blue jeans, black sneakers and a black glove on one hand.

Authorities said he is always armed with a small handgun.

Authorities are asking for the public's help and a $10,000 reward is being offered for information that leads to the man's arrest.
